Often when transmissions start to go reverse is the fist to go. Could be the transfer case but I doubt it. Unless you're seriously mechanically inclined I would recommend seeking out a good transmission repair shop and seeing what they think.

Im sorry for this bad news but It seems like you need a major tranny job. I would go for an used one. Don't spend money trying to fix this problem doing something else because that's just like putting it in the trash can. Im sure your tranny has gone bad.

Inside this type of transmission reverse is applied with a special clutch band, that band is usually the first thing to wear out in any automatic transmission, no reverse is a very common failure and I see it often on FixYa, the only solution is to overhaul the transmission, since replacing the reverse band requires the transmission be completely disassembled.

i think your on to something with your battery. Have your battery, alternater, and starter checked for free at most local parts stores,It could be other things as well but that's an easy and common problem to check first

Check the fuse, first. The reverse light switch on/in the transmission may also be bad. One of the bulbs in the back may have shorted out and blown the fuse. These are the most common causes. Look for a cut/broken or shorted lead harness "hot" wire going to the backup lights under the vehicle. The other thing to check are the grounds. In high humidity areas and places that use salt on the roads in winter, wiring can be attacked by the corrosive salt and moisture, eating away the terminals and wiring over time. Hope this helps...

make sure engine stays off for a while to cool engine. with a 10mm socket and long extensions and ratchet, remove the top Shroud there should be about 8 bolts, then remove top and bottom hoses, you'll need to probably buy new clamps, then remove with proper tool, the two lines from the transmisstion that are both on one side of the radiator. fairly easy, just takes a little time. good luck
